hide mesh or change material in reflections

I want to keep reflections and hide the mesh. Or in other words, I need to show a textured mesh. The example looks like chrome but I want like a car with a polished dark color.
Could I change the material in the above example?
Thanks

I'm playing around with settings as:http://www.andersriggelsen.dk/glblendfunc.php
but as you can see in the images...through the doors etc. the provisionally textured airplane is visible. The mesh for/with reflections is in front and even the water etc. is visible through but not the mesh behind.
Many thanks for any help.
